Oil-spills due to release of crude oil from tankers, offshore platforms, drilling rigs, and wells, and of other products such as diesel and bunker fuel, if uncontrolled, may have serious and sometimes long term environmental impact. This paper presen

Use of aqueous glycerol solutions provides a convenient approach for investigation of a variety of aspects of two phase flow phenomena in porous media concerned with viscosity. These include the scaling of spontaneous imbibition and the forced displa

The spreading of multi-component oils on water has been investigated by direct observations and predicted from measurements of the interfacial tensions and surface tensions of decane, toluene, heptane, and their mixtures. Pure decane does not natural

Here we study the formation of sterically stabilizing “hairy” surface layers for a series of styrene–butylacrylate and styrene–butadiene latexes copolymerized either with acrylic acid (AA), methacrylic acid (MAA), itaconic acid (IA) or acryla

Measured viscosity vs. shear rate relationships were analyzed for a wide variety of carboxylated latexes reported in the literature using the theoretical model proposed by one of the authors. The theory contains three main parameters: c m , k o and

The conductivity and dielectric constant of solutions of bitumen in toluene were determined for bitumens of differing asphaltene content. The results show that the conductivity is primarily controlled by the asphaltene content while the dielectric co

The Evotherm warm mix process is the direct substitution of the asphalt binder with a cationic asphalt emulsion. The field trial in Canada demonstrates 30 °C and 60 °C reduction in the mix and compaction temperature, respectively, than the conventi
